So there's a list being made of Non-SAAS Software. What is that? It's software that does not require a subscription. So, you buy it once and you're done. Do you have an old machine that still performs certain tasks well? Well, you can keep that 10 year old software on it, because it's not SaaS.
The website is No Sassy. No Software As Service, but in a Sassy way. Some links are for free software, other paid, but all of it "installable" and more or less "ownable."
More information on SAAS: Software as a service is a business model to keep a steady income stream. While it's great for those running the software, it can be completely detrimental for the average user simply by cost alone. Long-term costs are incredibly high for SAAS.
